CONTROLLING DEVICE.

Application iiled October 15, 1924. Serial No. 743,745.

T all whom it may concern:

Be it known that I, Girznnn Fnmn, a citizen of the United States,residing at Seattle, in the county of King and State of ashing-ton, haveinvented a certain new and useful Improvement in Controlling Devices, ofwhich the following is a specification. I

My invention relates to improvements in a controlling device and one ofthe objects of my invention is to provide controlling device that isadapted to be operated by the use of one hand of an operator forcontrolling the hoisting and lowering means and the braking means of ahoisting and lowering apparatus whereby either one of the hoisting orlowering means or the braking means may be caused to be inoperativewhile the operative position of the other is maintained or wherebyeither one hoisting or lowering means or the braking means of thehoisting and lowering apparatus may be caused to be operative while theinoperativeposition of the other is maintained or whereby the brakingmeans may be caused to be operative while the direction in which thehoisting and lowering means is being reversed.

Another object is to provide a hoisting and lowering device embodying alever arm arranged and mounted upon a shaft which shaft and lever armhave means attached thereto for controlling the lowering and hoistingmeans and the braking means of the hoisting apparatus said controllingmeans for the lowering and hoisting means and the braking means being soassociated with said lever arm and shaft, that a load may be raised to adesired position and there be held in such raised position by means ofthe braking 'means while the raising means is caused to be inoperativefrom which position the lever arm may be moved to a position to causethe lowering mechanism to operate to lower the load and from thisposition the braking means may be gradually released thereby loweringthe load at a desired speed. v

I accomplish these objects by devices illustrated in the accompanyingdrawings, wherein Figure 1 is an isometric view of the controllingdevices constructed in accordance with my invention; and

Fig. 2 is a plan View of the same illustrating by broken lines severalpositions into of the which the controlling lever may be moved.

One preferred use of my controlling device is in connection withhoisting and low-- ering apparatus for handling heavy and bulky logs,which hoisting and lowering apparatus is operated by means of anelectric motor having a controller for controlling the direction inwhich the motor is to be run and for controlling the speed at which themotor is to be run. 7 i

The motor is connected with a suitable winding drum having suitablebrake means (not shown) preferably operated by com pressed air. It isdesirable to use apparatus of this nature for the reason that inhandling logs the weight'of the same vary and it is necessary to providean apparatus that is capable of handling loads of varying weights. Itwill be understood that my controlling device may be associated withsteam or air operated hoisting and lowering apparatus and with steambrake means for said hoisting and lowering apparatus.

'Referring to the drawings, throughout which like reference numeralsdesignate like parts, 5 indicates the housing of a controller which may.control a supply of motive agent to a prime mover, as the supply ofelectric current to a motorvor steam to an engine and 6 indicates avalve in a pipe line 7 that may control a supply of motive agent, ascompressed air or steam, to a brake that is associated with said primemover.

The valve 6 has a crank arm 8 connected by a link 9 with a crank arm 10on a shaft 11 that is mounted for oscillation in bearing brackets 12.

The controller 5 is arranged to be operated by a pinion 13 that mesheswith a gear segment 14 on a shaft 15 that may be supported in bearingmembers 16. The shaft 15 is connected by a lever arm 17, link 18 anduniversal joint member 20 with an operating lever 21 that is connectedby pivots 22 with a sleeve 23 on the shaft 11, thepivots 22 beingarranged at right angles to the shaft 11 so that the operating lever 21may be moved on the pivots 22 in the longitudinal plane of the shaft 11.

The connections hereinbefore described and illustrated in theaccompanying drawings make possible the universal movement of theoperating lever 21 any movement of said lever longitudinally of theshaft 11 on pivots 22 producing an adjustment of the controller 5 andany movement of said lever 21 in a direction at right angles to theshaft 11 imparting an oscillating movement to said shaft 11 and tendingto vary the adjustment of the valve 6. For instance, as suming thevertical position of the lever 21, as shown in Fig. l, to be neutral,then, movement of said lever 21 directly to the right Will actuate thecontroller to supply the motive agent for starting the motor in onedirection without changing the position of the valve 6, While movementof said lever 21 to the left will actuate the controller in a manner toreverse the running direction of the motor. Movement of the lever 21into the dotted line positions A or B, shoWn in Fig. 2, will operateboth the controller 5 and valve 6 and movement of the lever 21 into theposition C Will operate the valve 6 only, the pivotal connection of thelink 18 and lever arm 17 permitting the link to be swung to one sideWithout producing a strain thereon. The valve 6 maybe constructed sothat movement of the operating lever 21 in a forward direction from the"neutral position produces a setting or tightening effect upon the brakeWhile movement of the same to the neutral position releases the brakemechanism.

The lever 21 being free to be moved into any position makes it possibleto completely govern both the controller and the brake operating meanswith one hand and to get the desired speed from the motor and thedesired brake pressure upon theibrake at any time, and, further makes itpossible to start, stop, reverse or vary the speed of the motor Withoutreleasing the brake or to alter the condition of the brake Withoutchanging the operating condition of the motor.

This application for Letters Patent is a substitute application forapplication Serial No. 644,6 5, filed in the United States Patent OfficeJune 11, 1923.

The foregoing description and accompanying drawings clearly disclose apreferred embodiment of my invention but it will be understood that thisdisclosure is merely illustrative and that such changes in the same maybe made as are Within the scope and spirit of the following claims.

lVhat I claim is:

1. In a controlling device for controlling a prime mover and a brake, alever mounted for universal movement, brake control means operated bydisplacement of said lever in one direction and prime mover controlmeans operated by movement of said lever at substantially right anglesto said first named direction.

In a controlling device, a lever mounted for universal movement, primemover controlling devices, brake controlling devices and meansconnecting said lever With both of said controlling devices whereby anydesired adjustment of both controlling devices may be securedsin'iultaneously by the manipulation of said lever.

3. In a controlling device, a lever mounted for universalmovement, acontroller for prime mover, brake controller means, a link connectingsaid lever and said prime mover controller device, and another link atsul stantially right angles to said first named link connecting saidlever and said brake controller means.

4:. In a. controlling device, a controller for a prime mover, a. brakecontrol device, a shaft mounted for oscillation, a crank arm on saidshaft, a link connecting said crank arm and said brake control device,lever secured to said shaft by pivot means disposed at right angles tothe shaft, and another link connecting said lever With said prime movercontroller.

5. In a controlling device, a controller for a prime mover, a brakecontrol device, a. shaft mounted for oscillation, a crank arm on saidshaft, a. link extending at substantially right angles to said shaft andconnecting said crank arm and said brake control device, a lever pivotedto said shaft by pivot means disposed at right angles to said shaft, andanother link arranged substantially parallel With said shaft andconnecting said lever With said prime mover controller.

In Witness whereof, I hereunto subscribe my name this 9th day of OctoberA. D. 1924.
